SAFETY-CATCH.

Specification of Letters latent.

Patented Nov. 11, 1919.

Application filed June 9, 1917. Serial No. 173,749.

'of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.

This invention relates to improvements in safety catches used on ins, brooches and the like, and has for its object to provide a catch of this character designed more especially for use on very small articles ofjewelry; and to provide a lock member slidable in said body closing the mouth of the opening pin-tongue.

It is found in practice that where the ordinary style of hook-shaped catch is attached to small articles of jewelry which are very delicate in construction such as those provided with enameled faces or the like,

that the springing of the pin-tongue out of its natural alinement to carry it into a hookshaped catch, often twists and breaks or cracks the enamel thereby destroying the beauty of the pin. Then again the ordinary form of safety catch has operating means so small as to be impractical for proper manipulation. To overcomethese objectionable features, I have provided an opening in the outer edge of the body of the catch. member and have mounted a longitudinally slidable lock bar in this body member, which may be simply pressed by the finger nail of the user on one side to move it to open the mouth of the slot and on the opposite side to close the slot and lock the pin-tongue securely therein.

The invention further consists in the offsetting ofv one portion of the lock bar thereby providing a yieldable frictional resistance to hold the bar in adjusted position.

With these and other-objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view showing my improved safety catch as mounted in operative position on the back of a thin plate to receive the pointed end of the pin-tongue.

Fig. 2 is a view of the inner face of the body plate as cut and swaged out of sheet metal.

Fig. 3 shows the plate illustrated in Fig. 2 as folded upon itself the sides being left slightly apart to permit the lock member to be positioned between the folds before being finally closed together.

Fig. 4* shows the sides of the body illustrated in Fig. 3 as having been closed tightly together.

Fig. 5- is a section through the body member on line 55 of Fig. 8.

Fig. 6 is an edge view of the lock frame showi thereo therein, to prevent accidentalrelease of the g the offsetting of one of the arms Fig; 7- is a side elevation of the lock frame. V

blg. 8 is a sectional side elevation showing the lock frame mounted in the body member and in unlocked position.

Referring to the drawings, 10 designates the body member which is formed prefer- 1 ably of a plate or strip of sheet metal and when struck up has a rectangular central I opening 11 through it and a raised edge 12 formed all around this opening; also its vend edges 13 and 14 are raised from the pl'aneof the surface 15 to substantially the same height as that about the center:

opening.

This plate is then folded at its middle upon itself as illustrated in Fig; 3 leaving the sides 16 slightly apart to permit the lock bar presently described to be positioned therein.

The folding of this plate causes the opening 11 to form a slot 17, see Fig. 8, in the outer edge of the body portion at the fold, for the reception of the pointed end 18 of the pin tongue 19, and the bringing to gether of the two sides 16 causes the raised portions 12, 13 and 14 to abut, the depressed portions 15 then forming two longitudinal grooves or channels 20 and 21 through this body member for the reception of the lock member 22.

This locking frame or member 22 is preferably formed of thin sheet springy stock out out into substantally a hollow square having an opening 23 thereinto. One of the legs 24 of this frame is preferably offset out of alinement with the other members of the frame, whereby when this frame is positioned in the bOdy member and the sides 16 i of these l of t'he l'atter arelclosed togetherflthe spring" egs cause a frictional resistance tedxlo this f ame, whi h se v a to v. fe fo 1; :-'i tziii'r zadjilsted ipes tiou wh ther, 5 open or closed andprevent it from moving without being manipulated by the Weave-r, and the raised portions 1 2,on the inner t faqes'fbi the 'isides serve 3 as stops to. limit the movement-of the lock in both directions.

The foregoing 'descriptionl is directed solely;- toward the constructioir illustrated, but I desire it tobe understood that I reserve the privilege of resorting to all the mechanical changes to which the device is -susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim: j i 1 1; A safety catch comprising a body memberrformed of a plate folded upon itself to fornr-side Walls said folded body being slotted inwardly from its margin, a looking 'ineni'ber sl idable between the folds of said plate and, having an arm adapted to close said-slot, and abutting aorti-ons raised on the inner surface of sai finitely determine the space between said folds which the locking member slides.

2. A safety catch comprising abodyinember formed off-a plate folded upon itself -to form side W-al'lssaid folded body being slotted inwardly fronr its anargin,'a looking plate slidably mounted to slide between said-folds and provided with an arm adaptedto close said marginal "slot; the stock plate to debetween saidjfoldsaibout sai-el slot being raised to provide a stop to limit the sliding "movement of said look, and a portion of said lock plate being offsetfrom the plane of the rest; of the plate to friotionally retain the lock in adjusted position.
